What's your method for quickly balancing equations? Somehow, under time pressure these questions give me trouble....

there is really no easy way to balance it except doing it through practice. usually i just make a table on both sides and try to balance it that way. :/ sucks

Ch3OCh3 + O2 = H20 + CO2


left side = 78 g

right side = 52 g


To get both weights equal, multiply the left side by 2 and right side by 3.

How do you know which coefficients go where?
